BOILER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 350,099, dated October 5, 1886.

Application filed January 28, 1886. Serial No. 190,117.

To all whom, it may concern.-

Be it known that I, EDWARD F. BARBER, a citizen of the United States, residing at Ionia city, in the State of Michigan, have invented a certain new and useful Boiler Attachment for \Varming Ash-Pans and Extinguishing Fire in Ash-Pans on Locomotives or Engines; and I do hereby declare that the following is a full, clear. and exact description of the invention, which will enable skilled mechanics to make and use the same.

My invention relates to devices for throwing water or steam, or both, into the ash-pan of a boiler for the purpose of thawing out the ashes therein, and for the further purpose of extinguishing what fire there might be in the ash-pan alter dumping the grate.

In the drawings, Figure 1 is an end view of a boiler with my improved attachment; Fig. 2, a side view, partly in section; and Fig. 3, an enlarged sectional view of the valve or controlling device.

At any suitable point near the top of the boiler K is inserted a double or two-way cock or valve, A, which is provided with steampassage a, water-passage I and chamber 0. The valve is further provided with valve-plugs B O, by which the supply of steam and water to the chamber a is controlled.

A pipe, J, screwed into the lower end or neck of valve A, communicates with the passage b, and extends down into the water in the boiler, as shown in Fig. 2, while a pipe, D, communicates with the chamber 0 and extends down along the end of the boiler, as shown in Figs. 1 and 2. Pipe D extends down to the bottom of the ash-pan F, near one side, and is carried along one wall thereof, on the inner side, as shown in Figs. 1 and 2, the pipe be ing perforated along one face within the ash pan. A second pipe, E, communicates with pipe D above the ash-pan, and extends along the inner face of the latter on the side opposite to pipe D, this pipe E being also perforated within the ash-pan.

H indicates the slatted bottom of the ashpan; I, arms connected thereto, and L the lever for dumping the ash-pan bottom.

(No model.)

M indicates the lever by which the grate is shaken; but inasmuch as these features form no part of the present invention they need not be described in detail.

\Vhen the ashes become frozen hard and caked in the aslrpan, it is impossible to dump them, and hence it is desirable to throw steam upon the ashes to thaw them out. This is done by simply closing passage 1) and opening passage a, whereupon the steam passes through a into 0 and through pipes D E into the ashpan, where it is discharged from said pipes, as shown in Fig. 1, the pipes on the opposite sides discharging toward each other entirely across the ash-pan.

\Vhen it is desired to discharge water into the ash-pan for the purpose of cooling the. hot coals, the passage a is closed and passage b is opened. The steam pressing upon the water forces the same up through pipe J, through passage b, chamber 0, and into pipe D, from which it is discharged the same the steam. By opening both valves B O steam and water will both be forced into and through pipe D and discharged into the ash-pan.

\Vhat I therefore claim as myinvention, and desire to secure by Letters Patent, is

1. I11 combination with a boiler and an ashpan therefor, a two-way valve, A, cominunieating with the steam-space and the waterspace of the boiler, and a pipe connected to said valve and extending into the ash-pan, whereby either steam or water, or both, may be discharged into the ash-pan at will.

2. In combination with boiler K and ashpan F, a \alve, A, communicating with the steam-space ot' the boiler, a pipe, D, connected to valve A and extending into the ash pan, a pipe, J, connected to valve Av and communicating with the water space of the boiler, and valveplugs B C, for controlling the discharge of steam and water, substantially as shown.

EDWARD F. BARBER.
